TOOL FOR CORRUGATING ROLLS.

SPECIFICATION forming part of Letters Patent No. 312,922, dated February 24, 1885.

(No model.)

To all whom it may concern:

Be it known that I, THOMAS H. STEVEN- SON, of Greensburg, in the county of Decatur and State of Indiana, have invented a new and useful lmprovement in Roll-Dressing Devices, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a perspective view of my im proved roll-dressing device. Fig. 2 is a perspective view of the adjustable carriage, and Fig. 3 a perspective view of the lateral adj ustable toolholder.

The present invention relates to an im provement in a devicefor dressing rolls.

In the devices at present in use great difii culty and annoyance are experienced, where spiral corrugations are desired, in forming said corrugations at equal distances apart and gaging them to a proper depth.

My device consists of a pair of end supports having radial arms designed to rest upon the journals, said arms being connected by means of winding ways. A sliding carriage having thereon a lateral adjustable tool-holder is designed to operate within the ways from end to end on the periphery of the roll, all of which will be fully set forth in detail.-

In the accompanying drawings, A represents a roll of any ordinary pattern designed to be operated upon. Apair of end supports, 13, the lower side provided with a semicircular recess, 0, have at their upper side a pair of radial or branching arms, D. The recess 0 is designed to be sufiiciently large to receive therein the journal E. These end supports are designed to be placed at a snflicient distance apart to receive between them the body of the roll A, with the said supports resting upon the journals. Winding pieces, F, having inward Ways G. These ways are secured firmly to the outer ends of the radial arms I). NVithin the ways G an adjustable carriage, I'Lis placed, desi ned to operate from end to end thereof by means of'the handle I placed at one end. Centrally within this adjustable carriage I provide a I next provide a pair of pair of transverse segmental ways, J. Laterally near one end an upright arm, K, is provided, having near the upper end a threaded opening, within which is placed a screw-guide, L, having at the outer end a crank, M. Midway between the ways J, I provide an opening or transverse slot, N. Through the adj ustable carriage H a lateral adjustable tool-holder, 0, segmental in form, is placed within the ways J. Outward] y from the slot N, I provide an adjustable tool-holder, P. Cutters or formers,ofany pattern desired,are designed to besecured in any suitable manner to the innerend of the holder P. Inwardly from the arm K, I provide a piece or a head, Q, hinged to the upper face of the lateral adjustable holder,- having a threaded opening to receive the screw-guide L. By means of this said screwguide L the adjustable piece 0 may be moved laterally, as desired. By means of the thumb piece R the tool-holder I? may be moved inwardly or outwardly, as desired, in gaging the depth of the cutter. By means of the han dle I the said carriage carrying the cutter or former may be moved backward or forward along the periphery of the roll.

Any suitable means may be used to secure the roll and this device in position relative to each other, as that is not within the province of this application.

\Vhat I claim is 1. In a device for dressing corrugated rolls, a winding guidoway carrying thereon an ad- .justable'earriage having bits, substantially as herein set forth.

2. In a device for dressing corrugated rolls, a winding guideway, as shown, having a carriage carrying a lateral adjustable tool-holder and removable bitholder, substantially as and for the purposes herein described.

In testimony that I claim the foregoing I have hereunto set my hand,this 3d day ofMay, 1884, in the presence of witnesses.

THOMAS H. STEVENSON.
